| 摘 要： | 采用HPLC建立了一种林业常用除草剂咪唑烟酸在土壤、水及杂草植株中的残留检测方法。土壤及杂草植株样品用甲醇+0.1mol/L的NH4HCO3水溶液(体积比70∶30)提取,水溶液样品直接用二氯甲烷萃取。 添加法测定结果表明:当添加水平为0.1~5 mg/kg时,平均回收率为86.9%~103.5% 。在土壤及杂草植株中的最小检知浓度分别为0.05、0.1 mg/kg;水中最小检知浓度为0.01 mg/L。

| Abstract: | A method for determining residues of the forestry herbicide imazapyr in water, soil and weed plant was founded by means of HPLC. The samples in soil and weed plant were extracted with methanol plus 0.1 mol/L NH4HCO3 water solution, but the sample in water was directly extracted by dichloromethane. The average recoveries for all fortified samples (0.01~5 mg/kg) were 86.9%~103.45%. The minimum detectable concentration of imazapyr was 0.05、0.1 mg/kg and 0.01 mg/L in soil, weed plant and water, respectively. |
